... PPTA timeline . ... List of projects . ... RedGW . ... One of the main goals of pulsar timing array projects is to limit the existence of a background of gravitational waves (GWs). Jenet et al. (2006) developed a method to determine such a limit if (and only if) the pulsar timing residuals were statistically white. In the paper we used data from six pulsars from the PPTA project to obtain a limit. The remaining pulsars were rejected because their timing residuals were not white. ...

... This task operates on event data in an event list. ... In the first two cases, the celestial coordinates of the reference point are taken respectively as the values of the RA_NOM , DEC_NOM or RA_OBJ , DEC_OBJ values in the input event file header. ... Although the OM attitude information may be more accurate, it will not be present throughout part of the observation, and as such, the default source for the attitude data should be "ahf". ...

... Description . ... The SCORPIO-2 project: . ... The multi-mode spectrograph SCORPIO-2 was developed using the experience of observations at the 6-m telescope BTA with the SCORPIO focal reducer . ... The focal reducer consists of several units ('floors') mounted in the common case in the following order (from the telescope focal plane): . ... The focal reducer is connected with the platform-adapter which used for guiding by offset stars and for illumination the spectrograph by calibration lamps. ...
